N:1 Multi mapping Not working !!

Question

Hi Guys,
I have input xml message structure as follows:
<ROOT>
    <OUTPUT>    ----------------------0..n
        <XQ_Segment>  ---------------- 0..1
                XQ_DATA  -----------------0..1
                XQ_Value  -----------------0..1
         </XQ_Segment>
         <DTM_Segment> --------------0..n
             <DATES>         --------------0..1
                   Receiving_Date --------0..1
                   Process_Date   --------0..1
             </DATES>
          </DTM>
      </OUTPUT>
  </ROOT>
like 'n' number of input message ---> mapping into target message (both side message structures are same). Basically I am merging 'n' number messages. Using BPM working fine. Rather bundling 10 messages, 10 individual messages are coming out. I am using CollectTime patter.
Please can any give me their very good exposure how to map these source and target messages? Field level, Node level etc.,
Many Thanks in advance
Kind Regards
San

If Your souce Test message for Example is like given below
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
   <ns0:Message1>
      <ns1:MT_Test_Forum xmlns:ns1="http://YH1309/TestMapping">
         <Root>
            <Output>
               <XQ_Segment>
                  <XQ_DATA>data1</XQ_DATA>
                  <XQ_Value>value1</XQ_Value>
               </XQ_Segment>
               <DTM_Segment>
                  <DATES>
                     <Receiving_Date>dateReceive1</Receiving_Date>
                     <Process_Date>DateProcess1</Process_Date>
                  </DATES>
               </DTM_Segment>
            </Output>
            <Output>
               <XQ_Segment>
                  <XQ_DATA>data111</XQ_DATA>
                  <XQ_Value>value111</XQ_Value>
               </XQ_Segment>
               <DTM_Segment>
                  <DATES>
                     <Receiving_Date>dateReceive111</Receiving_Date>
                     <Process_Date>DateProcess111</Process_Date>
                  </DATES>
               </DTM_Segment>
            </Output>
         </Root>
      </ns1:MT_Test_Forum>
      <ns1:MT_Test_Forum xmlns:ns1="http://YH1309/TestMapping">
         <Root>
            <Output>
               <XQ_Segment>
                  <XQ_DATA>data2</XQ_DATA>
                  <XQ_Value>value2</XQ_Value>
               </XQ_Segment>
               <DTM_Segment>
                  <DATES>
                     <Receiving_Date>dateReceive2</Receiving_Date>
                     <Process_Date>DateProcess2</Process_Date>
                  </DATES>
               </DTM_Segment>
            </Output>
         </Root>
      </ns1:MT_Test_Forum>
   </ns0:Message1>
</ns0:Messages>
and You want to get the Target Message as
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
   <ns0:Message1>
      <ns1:MT_Test_Forum xmlns:ns1="http://YH1309/TestMapping">
         <Root>
            <Output>
               <XQ_Segment>
                  <XQ_DATA>data1</XQ_DATA>
                  <XQ_Value>value1</XQ_Value>
               </XQ_Segment>
               <DTM_Segment>
                  <DATES>
                     <Receiving_Date>dateReceive1</Receiving_Date>
                     <Process_Date>DateProcess1</Process_Date>
                  </DATES>
               </DTM_Segment>
            </Output>
            <Output>
               <XQ_Segment>
                  <XQ_DATA>data111</XQ_DATA>
                  <XQ_Value>value111</XQ_Value>
               </XQ_Segment>
               <DTM_Segment>
                  <DATES>
                     <Receiving_Date>dateReceive111</Receiving_Date>
                     <Process_Date>DateProcess111</Process_Date>
                  </DATES>
               </DTM_Segment>
            </Output>
            <Output>
               <XQ_Segment>
                  <XQ_DATA>data2</XQ_DATA>
                  <XQ_Value>value2</XQ_Value>
               </XQ_Segment>
               <DTM_Segment>
                  <DATES>
                     <Receiving_Date>dateReceive2</Receiving_Date>
                     <Process_Date>DateProcess2</Process_Date>
                  </DATES>
               </DTM_Segment>
            </Output>
         </Root>
      </ns1:MT_Test_Forum>
   </ns0:Message1>
</ns0:Messages>
Then do the Mapping as follows
Output(Change the Context to  Message1)----
>Output.
For all other fiels just do the direct mapping from source Root toTarget Root .and similarly for other fields
You can also refer this wiki as a reference to collect message and bundle then into one message using BPM pattern
